One of Oregon's more diverse climates, the Umpqua Valley can successful grow both cool and warm varieties. It's comprised of three distinct climatic sub-zones: 1) The Northern area around the town of Elkton enjoys a cool, marine-influenced climate. It receives around 50 inches of annual rainfall, making irrigation unnecessary. Pinot noir and other cool-climate varieties thrive here. 2) The Central area to the northwest of Roseburg has a transitional, or intermediate, climate where both cool and warm varieties do quite well. 3) The area south of Roseburg is warmer and more arid, similar to Rogue and Applegate valleys to the south, making irrigation necessary. Warm-climate varieties, including Tempranillo, Syrah and Merlot thrive here. |
